Abstract
The present invention relates to a negative electrode including a multi-protective layer and a lithium secondary battery including the same. The multi-protective layer is capable of effectively transferring lithium ions to a lithium metal electrode while physically suppressing lithium dendrite growth on the electrode surface, and does not cause an overvoltage during charge and discharge since the protective layer itself does not function as a resistive layer due to excellent ion conductivity of the multi-protective layer, and therefore, is capable of preventing battery performance decline and securing stability during battery operation.
